Spring Boot 注解启动的两种方式

1.@configuration @EnabeAutoConfiguration
@ComponentScan

[java] view
plain copy

<strong>package com.example.myproject;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.context.annotation.ComponentScan;

import org.springframework.context.annotation.Configuration;

@Configuration

@EnableAutoConfiguration

@ComponentScan

public class Application {

public static void main(String[] args) {

SpringApplication.run(Application.class, args);

}

}</strong>



2.@SpringBootApplication

[java] view
plain copy







<strong>package com.my.data.cache;

import org.springframework.boot.CommandLineRunner;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

/**

* 项目启动器

* @author wangbowen

*/

@SpringBootApplication//必须标注该注解才能扫描程序里面的注解组件

public class SimpleApplication implements CommandLineRunner{

@Override

public void run(String... args) throws Exception {

System.out.println("hello!Spring Boot");

}

public static void main(String[] args) {

SpringApplication.run(SimpleApplication.class, args);

}

}
